Abstract
The FM spectroscopy technique has been applied to two frequency-doubled Nd:YAG lasers to achieve absolute frequency stabilization against the hyperfine structure components of the rovibronic P(54) 32–0 iodine line at 532 nm. A fractional frequency stability of 2 × 10−13 τ−1/2 has been obtained for integration times in the range of 1 ms < τ < 10 s. For longer integration times the stability level remains below 10−13, reaching a minimum value of 4.6 × 10−14 at 100 s. This high stability level is, to our knowledge, the best value achieved against iodine lines by this locking method and for a fully transportable system.
